Evaluate gan discriminator using test set
WebJan 19, 2024 · In order to evaluate the performance of a GAN generator, you should use data it has not seen before, i.e. a test set. Therefore, it does make sense to have a … WebU-Net GAN is a recently developed GAN with excellent image-generation performance, which achieves state-of-the-art performance on several datasets . Based on BigGAN, U-Net GAN changes the discriminator to a U-Net structure. The encoder discriminates the input image globally, while the decoder discriminates the image pixels locally.
